PROPER INSTALLATION OF HOSE ENDS AND FITTINGS
Follow these best practices when installing fittings and clamps:
• Cut the tube or hose end square and clean. You may use a vise and
fine-tooth saw to facilitate a square and clean cut. Remove any burrs.
• For tubes, fittings are supplied. There are two types of fittings. Fittings
with release button (called push-in fittings) require you to only insert
tube until it bottoms. Fittings with nut require you to loosen nut
three turns, insert tube until it bottoms, then tighten nut.
• For PVC helix wire suction hose, feed hose through a two clamps, push
hose on over the barb until it bottoms against the barb, and tighten
clamps. Do not use lubricant on the tube end; it may leave a residue that
compromises the connection. You may, however, soak the hose end in
hot water for a few minutes before pushing the hose on the barb.
CAUTION: Always allow slack in all tube and hose lines. Never cause the
tube or hose to immediately bend from the fitting. Allow the line to enter
or leave from the fitting in a straight manner for several inches to ensure
proper connection, to relieve stress to the fitting and tube or hose, and to
allow ease of detachment and reattachment during maintenance or repair.
